To find the mass and volume of irregularly shaped object. One can use the balance to find the weight, and to find the volume of the object water should be poured in the beaker and note the level of water.
Answer:
Ans is 200 J
Explanation:
Given: Force = 20N
Distance = 10m
Work done = Force * displacement
= 20 * 10
= 200 J
Answer:
Potential energy = work done on the spring
= Force x displacement
= 15 N x 0.025 m
= 0.375 J
Answer:
The best statement would be scientific laws describe phenomenon that can be observed in nature. Sometimes, laws are related to principle defining and predicting a certain happening without explaining its nature. It is different with ‘hypothesis’ or ‘theory’ as it aims to answer only the ‘what’ (observation only)...
